Asteroids

Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet.

A near-Earth asteroid discovered in 2016 may have once been part of the moon — making it unlike any space rock we’ve ever discovered.

To prevent asteroid impacts, UCSB physicists suggest we slice up the space rocks using arrays of “penetrator rods.”

Blowing up an asteroid heading to Earth with a nuclear bomb could save the planet, according to new planetary defense simulations.

Astronomers have discovered an asteroid that orbits the sun in just 113 days, making it the fastest-orbiting asteroid in our solar system.

Using data from the OSIRIS-REx spacecraft, NASA has updated its predictions about the Bennu asteroid impacting Earth.

The first high-res heat emissions map of the Psyche asteroid suggests the hunk of metal might not be the core of a developing planet.

NASA is staging a week-long asteroid impact simulation during which participants will need to respond to a hypothetical impact scenario.

JAXA’s Hayabusa2 has successfully returned asteroid samples to Earth. Its next mission? Gather information that could help prevent an asteroid impact.

Using a bioreactor packed with bacteria could make space mining more efficient by speeding up the extraction of elements from rock.
